Which Hi-pass filter for G-SSL ???

[quote author="smallbutfine"]*not*at*all*[/quote]
I've decided to throw all that 12-position filtering aside and just make a insert for an external sidechain-filter.
My order for a dedicated Mnly M%ss*v# P8ss%v# goes out in a minute :thumb:

[quote author="Viitalahde"]This one:

existing 47k summing resistors        bypass switch         back to PCB
                                                /
                                           o--/   o--o
                                           |         |

                                       capacitor of choice

If you just want a HPF, this one works fine. I use mine all the time.[/quote]

A pot instead of the bypass switch enables fine tuning the amount of hp- very powerful in altering the carachter of the effect.

[quote author="smallbutfine"]ok my f*kin internet explorer kicked me while posting :evil: , so the answer ini short:

HOW TO USE ONLY ONE ROTARY:
HP filter schematic from steffen in gregs layout like here
http://members.cox.net/capstanrecording/Sidechain_Sch.pdf
If thrust original (like silent:art, only in an out)...

use 2 pole 7 pos switch for simple bypass, 3 pole for full hard bypass.

simple bypass (2 pole) :

Wire up pole 1 like for the HP from steffen, but begin with pos 2. short pos1 to pos2 (HP OFF in pos 1+2)

connect the sidechain in-signal (mono) to pole 2.
position 1 to thrust in.
position 2-7 to HP steffen in.

full hard bypass (3-pole):
like above...
connect the sidechain out to pole 3.
position 1 to thrust out
position 2-7 to HP steffen out.

Makes one panelswitch
THRUST,OFF, 60Hz, 90Hz, 130Hz, 200Hz, EXTERNAL

Full hard bypass with both output options on thrust from clintrubber (http://home.hetnet.nl/~chickennerdpig/FILES/API/sc-circ_thrst_01.jpg):
Requires 3 pole 8 pos rotary.

Wire up pole 1 like for the HP from steffen, but begin with pos 3. short pos1 to pos2 to pos3(HP OFF in pos 1+2+3)

connect the sidechain in-signal (mono) to pole 2.
position 1+2 to thrust in.
position 3-8 to HP steffen in.

connect the sidechain out to pole 3.
position 1 to thrust loud out
position 2 to thrust medium out
position 3-7 to HP steffen out.

Makes one panelswitch
THRUST LOUD, THRUST MEDIUM, OFF, 60Hz, 90Hz, 130Hz, 200Hz, EXTERNAL

Hope i got it all now :grin:

Kind regards and happy DIY

Hey Martin,

would 1x12 rotary be OK for the second combined hi pass filter option? Greg told me that Steffen high pass only needs one pole, not two. So if the THRUST only needs 1 pole, then I can get a 1x12 switch and move the stop to the eight position. I can't find any 2x8 or 3x8 rotary in my town.

I can't find any other posts about the switch for this filter. Does the 1 pole 12 position work?

I need to finish ordering the rest of the parts I need for my GSSL.

Could this work for the full hard bypass?

Seems to be hard to find a switch with 3 poles...
